PLOW.

SPECIFICATION forming part of Letters Patent No. 543,276, dated July 23,1895. Application filed March 11, 1895- Serial No. 541,353- (No Inodel.)

of Washington and State of Iowa, have invented certain new and usefulImprovements I in Flows; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to an improvement in plows, and more particularlyto the class known as rotary or revolving plows, the object being tosimplify and make more efficient plows of this character; andtheinvention'therefore consists in the construction, arrangement, andcombination of parts, substantially as will be hereinafter described andclaimed.

In the annexed drawings, illustrating our invention, Figure l is a sideelevation of our improved plow. Fig. 2 is an opposite side elevation ofthe same. Fig. 3 is a top plan view.

Like letters of reference designate like parts in all the differentfigures of the drawings.

A denotes the main platform of our plow, which may be of any desiredshape and size. On this platform is a suitable seat a for the driver.The forward end of the platform A forms the plow-beam A. Below the beamA is the wheel 0, whichis supported in the swiveling standard 0. Thisswiveled wheel is adapted to run freely in the furrow ahead of therevolving plow-disks.

. B denotes the main furrow-wheel, which is located immediately behindthe disks, and B the main land-wheel, said wheels being oftolerably-large size and situated opposite to each other. These wheels BB revolve on an axle attached to the main platform A.

E and F designate the rotary plow-disks. They are located alongside ofeach other at any desired angle, as shown, The disk E is carried by thesupporting-arm e, which is socured at its upper end to one side of thehinged plow-beam D, said beam being attached to the main beam A by meansof some suitable hinge d; and the plow-disk Fis carried by thesupporting-arm 'f, extending farther back than the arm e in order thatthe two disks may be properly placed relatively to each other. The disksE and F may be of any usual or of anovel construction, as may bedeemedmost suitable. The armfcarries at its lower end a furrow-cleaner G,which is in the shape ofa common breaking-plow with a straight cutter toclean the landside. This will be found to be a very useful adjunct forthe plow-disk. p

H denotes a lever-handle, which extends upward alongside of'the seat at,so as to be within convenient reach of the operator. This lever isfulcrumed on the platform A and extends below the latter. It is providedwith a spring-catch it, that engages the notched segment I, so as tohold the lever in any desired position of adjustment.

J indicates the draft-rod to which the team is hitched. This is locatedin a substantially horizontal position beneath the platform A, its rearend being pivoted to the lower end of the lever H, while its forward endprojects through the guide j on the front end of the plow-frame. Thisfront end of rod J carries a ring or other device, so that the team maybe easily harnessed thereto. 'A link or coupling K is pivoted to thelower end of lever H and also to the armf, so that in this way the innerend of the draft-rod is connected to the hinged plow-beam. A tongue ispivoted at the forward end of part A and plays up and down, as may berequired, but ithas no side movement.

The provision of the coupling-link K is a very important feature of ourinvention. It

' enables the pulling action upon the draft-rod to be transmitted directto the plow-beam and results-in depressing said beam. Every pound ofdraft action causes a downward pressure on the frame and disks, and thusenables the plow to run perfectly steady and holds the disks at thedesired or adjusted depth. The straight direct draft-rod J is a valuablefeature, arranged and operating substantially as set forth. By its usewith the adjustment shown all side draft is obviated.

L denotes a rolling cutter, which is carried by an arm I, the upper endof which is pivotally hung beneath the platform A, preferably near therear end thereof. The height of this wheel from the ground is adjustedby means of the lever M, that is fulcrumed on the platform A and pivotedto'the arm Z, said lever M having a spring-catch m to engage the toothedsegment M for the purpose of holding the lever M and consequently thecutter L in any desired, position. This wheel is placed at the desireddistance from the wheel B (see Fig. 3) to cut the way for one or morefurrows to be used in the next passing of the plow. ter is to act as asteadying-frame and take the side strain off the wheels B B. It willalso be observed that this cutter L will cause no additional draft, asit will lessen the draft on the forward plow-disk at next passing' Byour improved combination and arrangement of parts many advantages aresecured over the common construction of rotary and other plows. Thefront swiveled wheel is an advantage. Being placed in the furrow (whichis always level in the bottom) it obviates all the up-and-down throw ofa front wheel running on the land surface, especially when crossingfurrows or ridges, and also in finishing the land there can be nodropping of the wheel from the land into the furrow, and thereby aconsequent plowing at an uneven depth. The large furrow-wheel B is alsoa very useful feature. It runs in the furrow. It is the main stay tohold the disks in proper lateral position, and being directly behind thefurrow'cleaner G it acts in connection The main purpose of this rollingcut- 1. In a plow,the combination of the frame,

the hinged beam, the disks carried thereby, the adjusting lever for thedisks, the draft rod pivoted to said lever and the link pivoted to thelever and the beam, substantially as described.

2. In a plow, the combination of the frame, the hinged beam, the diskscarried thereby, the disk arms secured to the beam, the draft pole, andthe coupling link, substantially as described.

3. The combination of platform A, beam D, disks E and F, said disksbeing supported in arms 6 and f, secured to the beam D, the breakingplow G carried by the lower end of armf, and the draft pole J.

In testimony whereof we affix our signatures in presence of twowitnesses.
